Under certain circumstances, the Windows 2000 post-Service
Pack 1 (SP1) catalog file (Sp2.cat) that is included with Windows 2000 post-SP1
hotfixes may be incorrectly versioned. All Windows 2000 post-SP1 hotfixes that
had this problem have been repackaged to include an updated Sp2.cat
file.

If multiple Windows 2000 post-SP1 hotfixes are installed on
your computer and one hotfix has this Sp2.cat versioning issue, your computer
may be affected. Depending on the order in which the hotfixes were installed, a
newer hotfixed Sp2.cat file may be replaced by an older version.

The resolution to this problem is a two-step
process. In step 1, you install a tool that can help you verify if your
computer is affected by this problem. In step 2, you install an updated Windows
2000 post-SP1 catalog file that protects your computer from this
problem.

Microsoft has released a tool that can help you verify if
your computer is affected by this problem. This tool checks all Windows 2000
hotfixes that are installed on your computer to determine if any of your
current hotfixes are affected.

files continue to be valid.
